Seattle Public Schools placed a Garfield High School teacher on administrative leave pending an investigation into behavior on a recent field trip to New Orleans.

The district hired a former assistant United States attorney to investigate the incident. The investigation determined that “policies, procedures and protocols were violated by staff and chaperones” on the field trip, according to Seattle Public Schools.

One of the allegations triggering the investigation claims a male student groped two female students at night in a New Orleans hotel room and on a bus.

Complaints also include students seeing their teacher and chaperones drinking alcohol and a chaperone “visibly incapacitated” to the point of needing assistance in returning to his or her hotel room.

Another claim alleges that a chaperone engaged in “inappropriate contact” with a student while under the influence of alcohol.

Seattle Public Schools assembled a media conference Wednesday afternoon only to say they had no comment and that it was a “personnel matter.”

The district says Garfield staff was trained at the beginning of the school year on field trip rules and expectations.

The superintendent is considering what action to take against the teacher involved, which may include her firing.
